  "instructions": "Tollbooth OAuth2 Collector — unauthenticated mailbox for OAuth2 authorization codes. This is a community utility with no monetization.\n\n## How It Works\n\n1. An MCP server directs the user's browser to an OAuth provider, with `redirect_uri` pointing to the serverless callback function.\n2. After the user authorizes, the provider redirects the browser to the callback, which calls `store_code` on this collector via MCP.\n3. The originating MCP server calls `retrieve_code(state=...)` to pick up the encrypted code (one-time read, auto-deleted).\n\n## Tools\n\n- `store_code` — Store an encrypted authorization code (called by the serverless callback).\n- `retrieve_code` — Retrieve and delete a stored code (called by the originating MCP server).\n- `collector_status` — Health check showing pending code count and TTL.\n- `service_status` — Report the running build (incl. the deployed git sha) so a redeploy can be verified.",
